Description
CYclohexanol Derivativesr Production and Use Thereof TECHNICAL FIELD
This invention relates to novel cyclohexanol derivatives and their use.
BACRGROUND TECHNOLOGY
Angiogenesis is deeply concerned with occurrence of pathological processes o~ various in1ammatory diseases (rheumati.c diseases, psoriasis, etc.), diabetic retinopathy, tumors, etc. Therefore, it has been considered that inhibition of angiogenesis has a connection with therapy and prophylaxis of these diseases and several groups have searched for substances capable of inhibiting angiogenesis. For example, mention is made of research works for application of Protamine by Taylor [Taylor, S, et al., Nature, 297, 307 (1982)] and for use of heparin in the presence of cortisone by Folkman et al. [Folkman, J. et al., Science, 221, 719 (1983)]. Furthermore, patent applications have been filed directed to ascorbic acid ether and its re].ated compounds (JP-A-131978/1983) or polysaccharide sulfate DS4125 (JP-~-119500/1988) as compounds showing activity of inhibiting angiogenesis.
However, the activities of these compounds are not sufficiently satisfactory, and compounds having more satisfactory activity are desired.
OBJECT OF THE INVENTION
The object of the present invention lies in providing novel compounds having an action of inhibiting angiogenesis and an anti-tumor action, whose toxicity to hosts is low.
To attain the above-mentioned object, the present inventors have conducted searches for various compounds and evaluation of them. As a result, they found that cyclohexanol derivatives, chemically derived from fumagillol, hydrolysate of fumagillin which has been 2 ~
known as an antibiotic agent and an antiprotozoal agent, have a superb action of inhibiting angiogenesis and an anti-tumor action, and that they are less Loxic to hosts, thus the present invention has been accomplished.

BACRGROUND TECHNOLOGY
Angiogenesis is deeply concerned with occurrence of pathological processes o~ various in1ammatory diseases (rheumati.c diseases, psoriasis, etc.), diabetic retinopathy, tumors, etc. Therefore, it has been considered that inhibition of angiogenesis has a connection with therapy and prophylaxis of these diseases and several groups have searched for substances capable of inhibiting angiogenesis. For example, mention is made of research works for application of Protamine by Taylor [Taylor, S, et al., Nature, 297, 307 (1982)] and for use of heparin in the presence of cortisone by Folkman et al. [Folkman, J. et al., Science, 221, 719 (1983)]. Furthermore, patent applications have been filed directed to ascorbic acid ether and its re].ated compounds (JP-A-131978/1983) or polysaccharide sulfate DS4125 (JP-~-119500/1988) as compounds showing activity of inhibiting angiogenesis.
However, the activities of these compounds are not sufficiently satisfactory, and compounds having more satisfactory activity are desired.
OBJECT OF THE INVENTION
The object of the present invention lies in providing novel compounds having an action of inhibiting angiogenesis and an anti-tumor action, whose toxicity to hosts is low.
To attain the above-mentioned object, the present inventors have conducted searches for various compounds and evaluation of them. As a result, they found that cyclohexanol derivatives, chemically derived from fumagillol, hydrolysate of fumagillin which has been 2 ~
known as an antibiotic agent and an antiprotozoal agent, have a superb action of inhibiting angiogenesis and an anti-tumor action, and that they are less Loxic to hosts, thus the present invention has been accomplished.

2 ~ 3 ~ ~) Thus, adult male Spra~ue-Dawley rats (11 to 16 week old) were anesthetized with nembtal and locally anesthetized hy instillation of xylocaine eyedrops onto the eyeball. The cornea was incised to a length of about 2 mm at about 2 mm inside from the corneal c.i.rcumference by means of an injection needle, and a basic fibroblast growth factor (bFGF, bovine brain-derived, purified product, ~ & D Inc.) and a sustained xelease pellet containing the test sample were inserted side by side into the incision so that the bFGF pellet was located on the central side in the cornea. In the control group, the bFGF pellet and a sample-free pellet we.re inserted into the cornea. After 10 days, the cornea was observed under a stereoscopic microscope.
The results are shown in Table 1.
The sustained release pellets were prepared in the following manner. An ethylene-vinyl acetate copolymer (Takeda Chemical Industries, Ltd.) was dissolved in dichloromethane to a concentration of 8%. A 3 ~1 portion of the solution was air-dried on a glass dish, an aqueous solution of bFGF (250 ng) was then placed thereon and air-dried and, finally 3 ~1 of the above-mentioned ethylene-vinyl acetate copol~mer solution was placed further thereon and air-dried to give a sandwich sheet. This sandwich sheet was made round into a bFGF

Experimental Example 1 Angiogenesis inhibitory action by the rat cornea micropocket method Method of Evaluation :
Essentially the same method of Gimbrone et al. [J.
National Cancer Institute 52:413-419 (1974)~ was followed.
2 ~ 3 ~ ~) Thus, adult male Spra~ue-Dawley rats (11 to 16 week old) were anesthetized with nembtal and locally anesthetized hy instillation of xylocaine eyedrops onto the eyeball. The cornea was incised to a length of about 2 mm at about 2 mm inside from the corneal c.i.rcumference by means of an injection needle, and a basic fibroblast growth factor (bFGF, bovine brain-derived, purified product, ~ & D Inc.) and a sustained xelease pellet containing the test sample were inserted side by side into the incision so that the bFGF pellet was located on the central side in the cornea. In the control group, the bFGF pellet and a sample-free pellet we.re inserted into the cornea. After 10 days, the cornea was observed under a stereoscopic microscope.
The results are shown in Table 1.
The sustained release pellets were prepared in the following manner. An ethylene-vinyl acetate copolymer (Takeda Chemical Industries, Ltd.) was dissolved in dichloromethane to a concentration of 8%. A 3 ~1 portion of the solution was air-dried on a glass dish, an aqueous solution of bFGF (250 ng) was then placed thereon and air-dried and, finally 3 ~1 of the above-mentioned ethylene-vinyl acetate copol~mer solution was placed further thereon and air-dried to give a sandwich sheet. This sandwich sheet was made round into a bFGF
pellet. The test sample pellets were prepared by dissolving each sample in ethanol to a concentration of 20 ~g/2 ~1, mixing the solution with 6 ~1 of an ethylene-vinyl acetate copol~mer solution, air-drying the mixed solution on a glass dish and making the thus-obtained sheet round.

Experimental Example 2 C57BL/6 mice (a group consisting of 6 mice) were inoculated subcutaneously at the dorsolateral area with 2 x 106 M5076 cells, and then a test compound dissolved in a 5% gum arabic physiological saline solution was subcutaneously administered lO times in total, i.e.
1st, 2nd, 4th, 5th, 6th, 7th, 8th, 9th, 11th and 12th day after the inoculation. After 13 days, the major axis (a) and the minor axis ~b) of the tumor tissue were measured to determine the tumor size by the calculation formula of a x b2 x 1/2. The ratio of the tumor size thus calculated to the tumor size of animals in the control group was shown by T/C (~). The results are shown in Table 2.
